BARREL-HOOP.

peciflcation of Letters Patent.

Application filed January 31, 1914. Serial No. 815,806.

To all whom it may concern:

Be it known that I, ELLSWORTH E. FLORA, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Barrel-Hoops, of which'the following is a specification.

The primary object of my invention is to provide a construction of barrel-hoop whereby it may be made, in any desired thickness for adequate strength, of thin metal-strap material. To accomplish this purpose I take thin metal strap of desired width and use a suitable length to form therewith a hoop of two or more concentric layers, which I clench edgewise together, at intervals, thereby producing a practically solid hoop composed of a continuous length of the material.

In the accompanying drawing, Figure 1 is an edge view of a barrel-hoop of my improved construction; Fig. 2 is an enlarged edge view of a broken section of the hoop showing the joint formed by clenching together the ends of the concentric layers, and Fig. 3 is an inner face view of the same; Fig. 4 is a perspective view of a barrel provided with my improved hoops, and Fig. 5 is an enlarged section on line 5, Fig. 4.

The hoop 6 shown is formed of two layers or thicknesses of metal strap .023 in. thick and ft in. wide; though the dimensions of the strap or number of layers used may vary for different sizes of barrels? for which the hoops are provided. These layers are clenched edgewise together at intervals to unite them into a practically solid hoop, the clenching being preferably performed in a manner that causes the joints 8 to present inner projections 8}, which, in driving the hoop into place upon a barrel, penetrate the wood and thereby secure the hoop in position, against loosening by displacement, without requiring any other fastening means to that end. The joint shown is formed by the tool of my patent No. 1,038,109, dated September 10, 1912, though any other suitable means may be used for the clenching purpose.

The advantage of my improvement is due not only to the cheapness. and facility with Which an adequately strong barrel-hoop, in every way fit for its purpose, may be produced, but 'it is particularly advantageous in enabling users to themselves manufacture the hoops and not be required to wait for filling orders for them to hoop-makers. The latter manufacture barrel-hoops in different sizes for the trade on orders therefor, and it is not uncommon for the user to be kept waiting several months for filling orders for special sizes. By my improvement, a user can provide himself with the necessary metal strap in reels, each carrying a continuous length of several hundred feet; andthe material may be readily taken, as needed, off a reel and hoop after hoop produced by cutting off the proper length of strap for each hoop to be formed, as described, of the desired number of layers and clenching the layers edgewise together, thereby saving the delays referred to in having orders filled.

The hoop shown in the drawings is formed Patented Mar. a, 1915. i

of only two concentric layers of the strapmaterial, though when the ends of the latter overlap at a joint, as represented at 9, three thicknesses occur. This is preferable to maintaining two thicknesses throughout the hoop, which might be done, however, by leaving unfastened the inner end section of the strap between the joint at 9 and that next adjacent on the right, to Fig. 1.

That I claim as new and desire to secure by Letters Patent is- 1. As a new article of manufacture, a hoop formed of a single length of metal strap coiled into a plurality of concentric layers clenched edgewise' rigidly together at intervals.

2. As a new article of manufacture, a hoop formed of a continuous length of metal strap in a plurality of concentric layers clenched edgewise' together at intervals to form joints presenting projections at the inner face of the hoop.
